And so here you can see it - some skins are used by more than one blog. This should be possible, it should not be unique. The error is because the table/some of the columns are unique. That is new, I guess. And it is crazy.

And it works now. But there are some blogs without a skin. So I looked in again - and I'm in trouble.
I haven't have blogs with an ID over 33. So why are the skin_ID over 33? There are some skins for feeds, but not so much that it would have an ID so high. Or isn't there a relation between the blog ID and the skin ID?

It is not possible for me to edit #12 - or better: to save my edit in #12. I can access and edit, but I can't save it (for community).

So the edit to post #12 will be here:

Edit:
I see, the skin_class and skin_name are the same, only the skin_folder is different. This seemed, because sometimes you could download the skin file folder after an update with the "_skin" at the end in its name (e.g. evocamp). I wish, there will be a notation for the names of skin folders. And a version number on the website with history so I can see, when the newest version was released and in which version of b2evo it will included (if it is included/bundled).
